JinkoSolar Holding Co., Ltd announced that the Company's polycrystalline modules passed PID test at 85 Degrees Celsius/85% relative humidity, following the success of passing potential induced degradation (PID) test at 65 Degrees Celsius weeks ago.
This achievement has made JinkoSolar the first company that passed both forward and reverse bias voltage tests under 85 Degrees Celsius/85% relative humidity, and was awarded with "Anti-PID" certificate at this condition by TUV-SUD.
During the testing period, solar modules were exposed to 1,000 volts of bias voltage under the condition of 85 Degrees Celsius/85% relative humidity. In order to pass this extreme test, the maximum degradation of power output between initial and final measurement should not exceed 5%. The tested Jinko modules have successfully passed the stringent requirements set by TUV-SUD.
"85 Degrees Celsius temperature /85% relative humidity is harshest known condition of PID test. Passing anti-PID test in this extreme environment solidly demonstrates the high quality of our selected base materials and encapsulation components, as well as our strict quality control of each production process. In addition, our consistent investment in R&D contributes to our success in PID tests and ensures the stable output of JinkoSolar's PV systems over a 25+ year life time," said Kangping Chen, CEO of JinkoSolar.
"The benefit to our customer is that PV systems built with our modules generate long-lasting top yields with the lowest PID power loss even under the most adverse conditions. This will ensure our customers the lowest claim rate and the shortest return on investment. This improvement in both performance and quality reliability is in line with our constant commitment to customers to keep 'Building your Trust in Solar'," JinkoSolar's Chief Marketing Officer Arturo Herrero added.
"PID is one of the phenomena that impose the biggest negative effects on the power output of solar plants. It is also a matter of great influence for buyers and investors since basic TUV certificates cannot meet their increasingly demanding and professional requirements," commented by Mr. Hailiang Xu, manager of PV Business Unit of TUV-SUD. "We are very pleased to see this achievement made by JinkoSolar. It assures us of the increasing awareness of Chinese solar manufactures to pursue the top quality of their products. TUV-SUD will continue to roll out programs that pose big challenges to the quality of solar products, which will help buyers identify the best suppliers and solar manufacturers gain stronger brand recognition in the solar market.
